It's that time of year again. The time when roughly 1,000 of the world's 20,000 remaining polar bears travel to Churchill, Manitoba (aka "The Polar Bear Capital of the World") to hunt for seals, and we — the Internet — watch. Because it is our duty. Because polar bears are awesome. And because explore.org has teamed up with Polar Bears international, Parks Canada, and Frontiers North Adventures to set up three live HD cams and bring us all the live polar bear action we can handle. Which, let's face it, is a lot.

Via explore.org:

Three live HD cams are situated atop a roving tundra buggy [one of these things; also pictured below], the tundra buggy lodge, and Wapusk National Park (which is one of the world's largest concentrations of polar bear maternity dens (where female bears give birth).

The point of the campaign is to raise global awareness around the impact climate change is having on the environment and animals in the north, and hopefully inspire a global "Groundhog Day" of sorts which will motivate people to improve the well-being of the planet.

Check out this year's highlights here, or watch the actual live broadcasts here. I've already got my three browser windows open. Do you? Pro tip: The best viewing times are between 8:30 and 17:30 Central Time.
